Abstract

Sandwich construction offers several advantages over monocoque and various discretely stiffened structures. These include greater load carrying ability, reduced weight, higher buckling loads and higher fundamental natural frequencies. The equations for the analysis and design of sandwich cylindrical shells subjected to beam type bending are presented herein. These equations are then manipulated to provide the face thickness, core depth, and core shear modulus to produce a minimum weight structure for a given load index and face material system. A factor of merit to select the best face material is also presented. As examples, Carbon/epoxy and E-glass/epoxy cross-ply composite faced sandwich shells are compared, as well as comparison with a monocoque cross-ply laminated shell.
梁式弯曲复合材料圆柱夹层壳的优化研究
夹层结构提供了优于单体结构和各种离散加强结构的几个优点。这包括更大的承载能力、更轻的重量、更高的屈曲载荷和更高的基本固有频率。本文给出了夹层圆柱壳在梁式弯曲作用下的分析与设计方程。然后对这些方程进行操作,以提供工作面厚度、岩心深度和岩心剪切模量,从而为给定的载荷指数和工作面材料系统产生最小重量结构。并提出了选择最佳面材的优劣因素。作为例子,比较了碳/环氧树脂和e -玻璃/环氧树脂交叉层合复合表面夹层壳,并与单壳交叉层合壳进行了比较。
